distinguished by its strongly rounded prothorax and its relatively 

 larger tarsal claws. A specimen submitted to Capt. Casey for de- 

 termination was returned as scapalis Lee, to which it bears scarcely 

 any similarity, except a remote resemblance in the arrangement and 

 coloration of its scales. Resembles also maculatus, but is more elon- 

 gate and the scales are more grayish or pale ochreous and arranged 

 differently. 



S» oriiatipeiiiiis n. sp.— Oblong-oval, piceous, anteunse and legs rufo- 

 piceoiis: scaly vestiture dense, consisting of rather large, oval scales, uniformly 

 yellowish gray on the underside, yellow and conspicuously mottled with spots 

 and areas consisting of larger, white scales above. Beak in the male rather 

 stout, somewhat tapering, longer than head and prothorax, slightly curved, 

 rather densely punctured and scaly in its basal half, somewhat shining be- 

 yond, scales intermixed with white erect setae, in the female longer than head 

 and prothorax, slender, shining, punctured and pubescent in its basal third ; 

 basal tufts conspicuous, incision deep; scrobes scarcely oblique. Antennae 

 slender, inserted one-third from the apex ( % ), or a trifle behind the middle ( 9 ). 

 second joint of funicie almost twice as long than the third. Head as in the 

 preceding species. Prothorax wider than long, moderately narrowed in front, 

 broadly but not strongly constricted at the apex, sides feebly rounded, hind 

 angles rounded, base feebly biemarginate; surface apparently densely, but not 

 coarsely punctured, punctures concealed by the dense, scaly vestiture, which is 

 only very feebly mottled with whitish on the sides, scales intermixed with erect, 

 white setse. Scutel triangular, moderately large, scaly. Elytra two-fifths wider 

 at the base than the prothorax, and nearly three-fourths longer than wide, sides 

 straight and parallel for one-balf their length, then gradually rounded to the 

 apex, humeri prominent, strife rather fine, punctures small, approximate; in- 

 terstices flat, setje erect, hair-like, conspicuous; the white scales are especially 

 conspicuous on a short basal line on the third interspace, less so in subquadrate 

 areas and spots on the disc. Prosternum deeply emarginate, with feeble, ante- 

 coxal ridges, postocular lobes prominent, completely concealing the eyes in re- 

 pose. Legs, tarsi and claws, as in the preceding. Length 3.25 mm. ; 0.13 inch.

Hnb. — California, Texas. A male and female specimen are before 

 me. Mr. Dike's and my collection. 



Distinguished from nebulosus by its more elongate, less robust 

 form and rather brightly ornate elytra, the postocular lobes are more 

 j)rominent, the scales are larger, more crowded, and the interstitial 

 setae quite distinct. 



S. Tallax n. sp. — Very similar in form and habitus to the preceding species, 

 but smaller and a little more robust; oblong-oval, black ; beak, antennae and legs 

 rufous, or rufo-piceous. Scales not crowded, rather small, oval, gray or yellowish 

 on the underside, yellowish and yellowish brown, variegated with lines of white 

 scales above. Beak : male, robust, curved, as long as head and prothorax, punc- 

 tured, with rows of erect setae, from base to about its middle, feebly punctured
